    Explorerinit phase of Boot sequences gets randomly prolonged

    Hi there,

    So recently I got a Dell XPS 15 9550. I immediately re-formatted it and install everything from scratch. I'm also only using Local Account for my laptop. Now weirdly, I've been experiencing several occasions where the Windows will get stuck at the Logon period (the one with my username) for as long as 30 seconds. I have no password btw. It happens randomly, every restart or cold boot.

    I then installed the Windows Performance Toolkit to boottrace my Windows. Using the Windows Performance Recorder, I tried to record my laptop in 3 consecutive reboots. 2 reboots are actually only taking around 10-12 seconds. However, the 3rd reboot took around 40 ish seconds. When I looked at the trace, I found out that on the 3rd boot, the ExplorerInit phase took as long as 30 seconds. On the other 2 boots, it only took around 1.5-2 seconds.

    Unfortunately I cannot upload the .etl files, as each measures 1.2 GB....... I can only post some of the screenshots.

    Anyone can help me with this? Or further analyze this data and solve it? Thank you so much.
